The invention relates to a method for detecting a traverse winding defect when winding a link (L) on a spool (1) rotatably driven about a longitudinal axis (X), the link (L) being alternately translationally guided relative to the spool (1) by a guide pulley (2) along said longitudinal axis (X) between two reversal positions, comprising: measuring the position of the guide pulley (2) relative to the spool (1) along the longitudinal axis (X) over time, measuring the position (P2) of a regulation device for regulating the advance speed of the link on the guide pulley over time, from said measurements, determining a deviation between the position (P3) of the regulation device and a reference position (P3r) at each reversal position (Pi1,Pi2), and from said deviation, detecting the formation of a hollow or bump in the winding.

Reversal mechanism for a rolling ring drive. A reversal mechanism for a rolling ring drive (10) comprising a motor (12) attached to an inner ring housing (16), a controller controlling the angle of the rolling rings via the motor (12) in dependence upon a sensor which detects the position of the rolling ring drive (10) and other desired parameters.

A motion drive system for controlling a rolling ring drive which comprises the steps of: determining the dead centre of the rolling rings to provide the operational mid-point for a stepper motor when reversing the rolling rings; establishing a start point; setting a first reversal point and a second point for reversal of the rolling ring drive which are defined in relation to the start point; determining the speed of travel of the rolling ring drive in dependence upon the material to be wound and/or the speed of the coiling; determining an end point for coiling depending upon the depth of coiling required or the amount of material to be coiled; from these, the pitch of the rolling ring is set by the system to achieve the pre-selected speed of travel.
